You should be able to see a escilator on there. You can see it on every other chip like D2Pro, Wasabi, D2Sun, it's the metal box on all these chips. That it's on the Wiikey2s website, well wouldn't be the first time, that they have lied about a feature...
Well in the end it doesn't matter. Imo the best chip at the moment is Wasabi and that has 9 wires. Simply, because it has no issues at all. All the other chips have.
The thing why I would never recommend a Argon is, that the team may have years of experience, but in this years they never got it right. It had issues on D2C and then MAJOR issues on D2C2, until they announced that they couldn't do D2C2 because Argon had no oscillaor and they wold do hardware redesign. Now all of a sudden an oscillator isn't a problem anymore.
But as I've heard fro the few that still install Argons it still has bigger issues than other chips.
Btw. that I can't even find their 7 wire firmware or an isntall diagram is just poor. I mean I looked really hard and just couldn't find it. How should anyone trust a team that can't even maintain a website to maintain a modchip.
And I wouldn't discuss about it if I wouldn't think that you are giving people ill advise. I don't like the wiikey2 and it's team in particular, but I would never say to someone they should stay away from it or discuss with someone who loves the chip...
